1 Claim.

This invention relates to a non-skid device for automobiles.

An object of the invention is the provision of an eiicient manually operated device on a motor vehicle for placing dry or heated sand on the surface, over which the motor vehicle is passing, preferably in front of the rear wheels of said motor vehicle.

Another object of the invention is the production of a sanding mechanism in which a peculiar valve device is employed, and which valve device is capable of being easily operated by the driver of the motor vehicle.

A sti11 further object of the invention is the construction of an efficient sanding mechanism in which a sliding valve device is employed, which valve device can be moved to an open position, for permitting sand to drop on the ground, by the operator simply pulling on a grip or throttle, preferably placed on the instrument board of the motor vehicle.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and. more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a View in side elevation of a motor vehicle, partly showing in full lines and partly in dotted lines the mechanism constructed in accordance with this invention.

Figure 2 is an enlarged, fragmentary view in elevation of the mechanism.

Figure 3 is a top plan View of a portion of a 3 motor vehicle, showing my improved mechanism assembled therewith.

Figure 4 is a horizontal, sectional view taken on line -L Fig. 2, and looking in the direction of the arrows.

Figure 5 is a vertical, sectional View taken on line 5 5, Fig. 2.

Referring to the drawings, in which the preferred embodiment of this invention is illustrated, I designates the floor of the motor vehicle, which constitutes the support for the sanding mechanism. A sand container 2 is secured upon the oor I, preferably in the rear portion of the mo tor vehicle 3; this container 2 is provided with a suitable Vcover 4. The iioor I and the bottom of the sand container 2 are provided with regn istering discharge openings 5, Fig. 5. Secured to the floor I, under the sand container' 2, are two valve guides 6, Fig. 4, each having an inwardly extending stop I at each end. A sliding valve it 2 is positioned between the guides 5. Valve 8 is provided with a valve opening 9, which is adapted to register with the discharge opening 5, when sand is to be discharged through opening I0 into the transverse casing I I (Fig. 5).

The sliding valve 8 is provided on its rear with an eye I2, into which extends eye I3 of rod I4 (Fig. 4); this rod M is provided at its outer end with a loop I5. Loop I5 is positioned in the hook IS, formed on the lower end of the flat, vertically extending spring I'l. Spring I'l is securely fastened at its upper end to the oor I. On the front end of the sliding valve 8 is an eye I8. A flexible wire I9 is fastened at its inner end to eye I8, the outer end of said wire la being connected in any suitable manner to the knob or throttle 20, Fig. 1.

An exhaust pipe 2| extends from the motor 22 to the transverse casing II, and through said casing (Fig. 5) and thence to the muler 23, shown in dotted lines, Fig. 1. By this single exhaust pipe extending through the transverse casing II, the sand is suiciently heated in the sand container 2 to make the sand free flowing.

The transverse casing II is provided with two downwardly extending chutes 24, which preferably are capable of discharging dry sand directly in front of the rear wheels of the motor vehicle, Fig. 1.

A bearing plate 25 is placed underneath the guides 5 and valve 8 and is located on top of the transverse casing II, Fig. 5. This plate 25 provides an eiiicient surface upon which valve 8 slides.

The valve 8 is normally held by fiat spring I1 in a closed position, Fig. 4. When the operator pulls on knob 20, the valve 8 is pulled forward, against the action of spring I'I, until opening 9 registers with the openings 5, whereupon sand is allowed to discharge into the transverse casing l I and thence into chutes 24.

The stops l prevent the sliding valve from having too much movement in either direction.

While I have described the preferred embodiment of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claim.

What I claim is:

The combination with an automobile having rear wheels, a loor and an exhaust pipe extending beneath said floor, of a sand box resting on plate heldt' the lower side of said guides, a main v sand ductvextending transversely of the automobile andfheld against said plate, said bearing plate and sand duct having registering openings aligned with the oor opening, said exhaust pipe extending along the longitudinal axis of and within the major part of said duct and close below said valve, and delivery nozzles extending downwardly from the ends of said duct to terminate in front of said rear Wheels.
